MACHINE FOR INFUSING COFFEE OR TEA.

SPECIFICATION forming part of Letters Patent No. 459,833, dated September 22,1891. Application filed December 18, 1890. Serial No. 375,092. (No model.)

To all whom it may concern:

Be it known that we, LUDWIG OHEONIK and AUGUST CHRONIK, both of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Iufus'ing Coffee, Tea, 850., of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine designed for infusing coffee, tea, and other similar substances, and which is simple and durable in construction and entirely automatic in operation.

The invention consists of a boiler hung on a counterbalanced lever and a lamp-extinguisher controlled from the said lever.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a front elevation of the improvement, with parts in section, and Fig. 2 is a side elevation of the same.

The improved machine is mounted on a suitably-constructed base A, on which are erected two posts B and B, preferably made hollow and connected with each other at their upper end by a bail B which serves to move the machine conveniently.

On the upper ends of the posts B and B is secured a skeleton frame 0, in which is held a receptacle D, adapted to contain the ground coffee, te'a,'or other substances to be treated. Into this receptacle D extends the upper end 'of a pipe E, provided within the receptacle D with a rose F to prevent the ground coffee from passing into the pipe E. The latter extends loosely through a slot D in the removable cover D of the receptacle D and passes at its lower end into the boiler G to within a short distance of the bottom thereof.

The boiler G is provided with an inlet G, adapted to be closed by a suitable cap, which, when removed, permits of introducing the necessary amount of water into the boiler G. The latter is provided near its lower end with a faucet H for drawing off the coffee, tea, &c.,

and is further provided with a gage I, indicating the level of the water in the boiler. The boiler G is connected at its top by alink J with the inner end of a lever J, fulcrumed at J on a bracket B connecting the two posts B and B with each other. The outer end of the lever J extends through a slot in the post B and supports a weight K, preferably extending in the hollow post B On the side of the boiler G are arranged the pins G extending into vertically-arranged guideways B formed or secured on the insides of the posts B and B and servingto guide the boiler G in its up-and-down motion.

In the base A, directly below the boiler G, is held a lamp L, of any approved construction, serving to heat the water in the boiler G. The flame of the lamp L is automatically extinguished, as hereinafter more fully described, by an extinguisher provided with a cap N, adapted to pass over the burner of the lamp L. The cap N is secured on a shaft 0, extending longitudinally in the rear of the posts B and B and mounted to turn in suitable bearings O, secured on top of the lamp L. A spring P is coiled on one end of the shaft 0 and is secured by one end to one of the bearings O on the lamp L and at its other end to a pin of the shaft 0. The spring P has a tendency to turn the shaft 0 insuch a direction as to move the cap N over the burner of the lamp L in order to extinguish the flame. The shaft 0 is provided at one extreme end with a knob or handle O -for conveniently manipulating the shaft, and the other end of the said shaft is connected with a tripping device controlled from the lever J, supporting the boiler G. This tripping device is provided with a disk 0 secured on 0 that the disk 0 as well as the shaft 0, with its cap N, are locked in position. The free end of the lever Q is formed with a fork Q,

When the shaft 0 has 5 adapted to be engaged at the under side by a collar R, held adjusted by means of a setscrew or other device on a rod S, passing through the fork Q of the lever Q. The rod S extends vertically and has its lower end guided in a fork S, projecting from the post B. The upper end of the rod S is connected with a lever T, passing through a slot in the post B and fulcrumed at T on the bracket B previously mentioned. The inner end of the lever T is pivotally connected by a short link U with the lever J at a point between the fulcrum J 2 and the connection of the weight K with the said lever.

The operation is as follows: When the several parts are in the position shown in Figs. 1 and 2 and the ground coffee, tea, or other substance has been placed in the receptacle D and the boiler has been filled with the necessary amount of water, then the weight of the boiler G, in acting on the lever J, causes the free end of the latter to spring upward until the free end reaches the end of the slot in the post B, as illustrated in Fig. 1. hen the operator now ignites the lamp L, heat emanating from the latter heats the water in the boiler G, so that steam is generated, which when it reaches a suflicient pressure acts on the remaining water and forces the latter through the pipe E of the rose F in and through the coffee-grounds, tea, &c., in the receptacle D. As soon as the water is thus discharged from the boiler G the weight K counterbalances the boiler G to its direct connections, so that the weight K sinks, while the boiler G rises. This movement of the lever causes a swinging of the lever J, which, by its connection with the lever T, swings the latter, so that the outer end of the said lever T rises, thereby moving the rod S in the same direction. The upward movement of the rod S causes the collar R to lift the lever Q, so that the projection Q, is disengaged from the notch O of the disk 0 and the shaft 0 is thus re leased. The action of the springPnow causes the turning of the shaft 0, so that the cap N passes suddenly over the burner of the lamp L, thus extinguishing the flame of the latter. The steam remaining in the boiler Gnow condenses, so that a vacuum is formed therein, which causes the infused liquid in the receptacle D to pass through the rose F and the pipe E back into the boiler G. The coifee, tea, or other liquid is then ready for use and is drained off from the boiler G through the faucet H. Thus it will be seen that when the lamp is once lighted, as previously described, no further attention is required by the operator until the liquid is finished, as above described.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. The combination, with the boiler and a counterbalanced lever supporting the boiler, of an extinguisher under the boiler and operating connections extending upward from the extinguisher beyond the boiler to the said counterbalanced lever, substantially as described.
